A renderer doesn't ship one image. It ships a stack of images — beauty, diffuse, specular, normal, depth, position — that the compositor relights, regrades, and recombines until the shot is delivered.

Beauty
Same teapot, six passes. The compositor reads them all. A scene ships when its AOV stack reads as physically plausible at every channel — not just at beauty.

Maya — the host. OSL — the shading language.
OpenEXR — the file format the AOVs land in. Nuke — what reads them.
OpenColorIO — the colour pipeline. USD — the scene interchange.
SHIP THE STACK. NOT THE FRAME.
